As everybody is saying, that's a crazy rate. And its a crazy rate even considering the costs of the chargers. A typical driver will use around 2,500 kWh in a year -- perhaps less if an urban driver. Some will be at fast chargers on road trips (and some like you will do it at work.) But with the electricity costing 20 cents (but should be much less at night) and 2,000 kWh that's $600 of margin per year which should pay for the stations pretty quick.
Though on the other hand, if they had to do a major renovation to put in the stations, re-pouring concrete, rather than just screwing conduit to the walls, it could add up to thousands per station. Some people definitely pay that.
Plus they probably foolishly tried to provide 7kW at every station so they had to put in 170kW or 700 amps of extra service which is pricey. There are many ways to avoid that:
- You don't need remotely 7kW at each station. The average car only uses 10kWh/day which means 2kW is more than enough as an average.
- There are tools which can share load. I am an investor in one company that makes a tool that lets you put in the 7kW for every car without increasing the service for the building, because it tracks the other loads in the building and lets the cars have what's left, and at night there is always plenty left. (It's at variablegrid.com) You can also share just among the stations and not need to put in so many extra amps
- They probably bought fancy charging stations which are much more expensive. You know why they bought them? Because they have billing ability. Yup, you are paying all that extra so they can bill you. I bet most tenants might prefer a flat monthly fee that's more than the base price but a lot less than 50 cents -- unless they are a very light user. How about $50/month to have a stall for yourself instead of paying that for only 100kWh?
This is a co-op so they should be trying for cost recovery, not profit.
